[LTO] Fix symbols which were internalized incorrectly. If a symbol is defined in an archive, when we replace its body the isUsedInRegularObj wasn't set correctly. Internalize makes its decision based on that bit so we ended up internalizing symbols that we shouldn't (because they're referenced). This should fix. Thanks to Peter and Rafael for discussion and help diagnosing the issue! Found during LTO of unittests. llvm-svn: 265208

[ELF] Remove -m argument to lld in test files. NFC. This should be correctly implied by the linker. This also makes the tests slightly easier to maintain and compare with the equivalent tests under for other platforms. Differential Revision: https://reviews.llvm.org/D47513 llvm-svn: 333567

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651

Reland "Change the X86 datalayout to add three address spaces for 32 bit signed, 32 bit unsigned, and 64 bit pointers." This reverts 57076d3199fc2b0af4a3736b7749dd5462cacda5.
